It makes a HUGE difference in my 12 1/2 yr old golden. Whether he is sore from chasing the ball or swimming in the pool; we have one every night before bed... These make it all go away the next day. Consistency is the rule here.

My senior dog goes absolutely nuts for these. They have way more Glucosamine and MSM than most other treats, and at iHerb they're much cheaper than at the pet store. I've ordered all the flavors- he can't get enough. An easy and relative inexpensive way to give joint supplements- try them!
